TDT Technology Offers New KAFO Machines – BMC 2012A

Available from TDT Technology is the impressive new line of KAFO BMC machining centres; since their recent addition to the TDT stable the machines have proven extremely popular among the UK manufacturing industry. 

Discussing the new line of machine tools, TDT Technology Ltd Managing Director, Mr Simon Hewson told MTDCNC: “These new machines are selling very well. They are particularly robust, rigid and very heavy. Furthermore, the new BMC 2012A machine is the most compact model that we do. It has a 2m by 1.1m table and a total weight in the region of 20 tonnes.”

With a single piece casting for its base and roller linear guideways, the machine will prove the ideal solution for the mould & die industry, the aerospace and general subcontract sectors and many more sectors aside.

From a space perspective, the new BMC 2012A has a travel of 2.1m by 1.2m by 800mm in the X, Y and Z axes with a distance from the spindle centre to the track surface of the Z-axis of 150mm, giving a total distance from the spindle nose to table from 150 to 950mm. Regarded as a particularly fast machine, the KAFO BMC 2012A pleasantly balances weight and rigidity with speed and flexibility. This is demonstrated with a maximum loading capacity of 4,000kg under the standard 15,000rpm BT40 taper spindle. As an option, the direct drive spindle units are also offered in variants from 10,000 to 18,000rpm with a BT50 spindle. 

“We can do a 90 degree head or a universal head with a manual changeover whilst the K-range variant offers completely automatic head changing. Whilst this particular machine is the smallest in the range, they can be offered with up to 10m in the X-axis whilst the KRV range offers travelling columns so we can achieve a Z-axis of up to 2.6m.”

The KAFO BMC 2012A generates rapid traverse rates of 20/20/15m/min in the respective X, Y and Z axes and the powerful machining centre has a 32 tool CAM driven magazine that can support tools with a maximum tool diameter up to 127mm. The tool changeover time is an impressive four seconds with a chip to chip time of seven seconds. Driven by a Heidenhain iTNC620 CNC control unit with the option of Siemens or FANUC control units, the BMC 2012A also incorporates a high torque 10kW spindle motor that makes this robust unit something certain to impress UK manufacturers. 

“KAFO have their own spindle manufacturing facility that ensures exceptional spindle life, uptime and reliability whilst the chip removal is extremely efficient with twin-augers on this machine. All the double column machines have coolant through the ballscrews to ensure there is no thermal expansion,” concludes Mr Hewson..
